Frequently Asked Questions
What is the difference between the Profi 550 and the Profi 550/700 models in the same series?
The number in the name indicates the distance between centers in mm — the maximum length of the workpiece that can be turned. Profi 550 mm. The 26 mm spindle bore indicates the maximum diameter of the bar that can pass through the spindle bore without turning. The Vario variator adds continuous speed adjustment compared to standard models in the same range.
What changes with the electronic Vario variator?
The electronic variator (Vario) allows continuous speed adjustment without stopping the machine — you can switch from roughing to finishing by turning a knob in 2 seconds. The torque remains high even at low speeds, unlike mechanical belt variators. On the Profi 550, it covers the full range indicated in the table without steps.
230 V power supply: is a transformer needed for the Profi 550?
230 V single-phase — it connects directly to the standard Italian industrial socket (Schuko 16A). No transformer or three-phase panel required. Suitable for private workshops, workshops without a three-phase system, and vocational schools.
Are spare parts and assistance available?
Original spare parts available with 3–5 working days shipping. Customer support in Italian available.
